Claims. l

This invention relates to window Ventilating checks used primarilir onwindow sills, and in particular a ventilator formed with a continuousinclined plate having a rolled upper edge and retained in position withsupporting clips having U-shaped clips on the edges which snap over theedge of a window sill for retaining the parts in position.

The purpose of this invention is to provide a window check or ventilatorthat is positioned on a Window sill without being permanently attachedto the window frame.

Various types of ventilators for windows have been used on window sills,however, where these are provided with frames attached by screws to theWindow frames it is diicult to remove the parts for cleaning. With thisthought in mind this invention contemplates a ventilator including acontinuous panel and supporting elements with spring clips on the edgeswhereby with the clips forced over the edge of a window sill the deviceis frictionally retained in position and may readily be removed andreplaced as desired.

The object of this invention is, therefore, to provide means for forminga window ventilator that is adapted to be installed without screws orother fastening elements.

Another object of the invention is to provide a window ventilator thatis adapted to be retained in position with friction clips, that isadjustable to windows of different sizes and that is adapted to be usedon windows without changing parts of the window frames.

A further object of the invention is to provide an improved Windowventilator that is frictionally secured in position on a window sill,which is of a simple and economical construction.

With these and other objects and advantages in View the inventionembodies a pair of supporting elements, V-shape in cross section withclips on the ends of the arms, a continuous panel adapted to be securedin said supporting elements, and wings adapted to be secured in thesupporting elements, and positioned to extend to meet the vertical railsat the sides of a window frame, with the supporting elements positionedon the sill of the frame.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawing, wherein:

Figure 1 is a perspective View illustrating the position of the improvedventilator on a window sill.

Figure 2 is a cross section taken on line 2 2 of Fig. l showing theventilator with parts of the window frame and sill omitted.

Figure 3 is a plan view of the improved window ventilator with partsbroken away.

Referring now to the drawing wherein like reference characters denotecorresponding vparts the improved window ventilator of this inventionincludes a continuous panel Iii, having a rolled upper edge ii,supporting elements having webs I2 extended upwardly from bases I3 withspring clips It on extended edges of the bases and with rolls I5 on theupper edges of the webs and positioned to rec-eive the roll on the upperedge of the panel lil, and wings I6 extended from the edges of the websI2 and positioned to close triangular shaped areas between theventilator and vertical rails of a window frame upon the sill of whichthe ventilator is positioned.

The base sections I3 of the supporting elements are in a common planewith the parts assembled whereby the bases are adapted to be positionedupon a window sill and the upwardly extended webs I2 of said elementsare also positioned in a common plane whereby the panel I0 is adapted torest upon upper surfaces of the inclined sections with the rolled upperedge II telescoping in the rolls I5.

The supporting elements are reinforced with triangular shaped gussetplates Il and I8, and as illustrated in the drawing, with the base ofeach of the supporting elements positioned on a window sill, asindicated by the numeral I9 the clips M at the outer edges of the basesfrictionally hold the supporting elements on the Window sill.

It will be understood made of plastic, metal,

that the parts may be or other suitable material and with the roll II onthe upper edge of the panel I0 nested in the roll I5 of the supportingelements the parts are frictionally held in assembled relation and alsofrictionally mounted upon a window sill. vBy this means the ventilatormay readily be removed from the window sill and the parts taken apartfor cleaning.

It will be understood that modifications within the scope of theappended claims may be made in the design and arrangement of the partswithout departing from the spirit of the invention.

What is claimed is: y

1. A window ventilator comprising alined V- shapo supporting elementshaving base sections with clips on extended ends thereof and inclinedupper sections with rolled upper edges, said inclined upper sectionsbeing in a common plane and a continuous panel extended between andsupported by said V-shape elements.

2. A window ventilator comprising alined substantially V-shape elementshaving horizontally disposed bases with spring clips on extended endsthereof and upwardly inclined webs the base and upwardly inclined web ofone supporting element being in the same plane with the base andupwardly inclined web of the other element, and a panel extended betweensaid V- shape elements, said V-shape elements having means forfrictionally retaining the panel in position.

3. A window ventilator comprising a pair of alined supporting elementshaving bases with spring clips on extended edges and having upwardlyinclined webs with rolled upper edges, the base and upwardly inclinedweb of one supporting element being in the same plane with the base andupwardly inclined web of the other element and a panel having a rolledupper edge positioned with ends thereof against the inclined webs of thesupporting elements and with the rolled upper edge thereof telescopingin the rolled upper edges of the inclined webs.

4. A window ventilator comprising a pair of alined supporting elementshaving bases with spring clips on extended edges and having upwardlyinclined webs with rolled upper edges, the base and upwardly inclinedweb of one supporting element being in the same plane with the base andupwardly inclined web of the other element and a panel having a rolledupper edge positioned with ends thereof against the inclined webs of thesupporting elements and with the rolled upper edge thereof telescopingin the rolled upper edges of the inclined webs, said supporting elementshaving reinforcing plates in the ends thereof.

5. A window ventilator comprising a pair of alined supporting elementshaving bases with spring clips on extended edges and having upwardlyinclined webs with rolled upper edges, the base and upwardly inclinedweb of one supporting element being in the same plane with the base andupwardly inclined web of the other element and a panel having a rolledupper edge positioned with ends thereof against the inclined webs of thesupporting elements and with the rolled upper edge thereof telescopingin the rolled upper edges of the inclined webs, said supporting elementshaving reinforcing plates in the ends thereof, and triangular-shapedwings extended from one of the ends thereof.
